Cant click on any image

Its been like this for at least a week and i still can click into any images. Doesnt work on firefox and explorer.

All of them. When im in the thumbnail screen it wont let me click on the images to make it bigger. It just stays there and the only thing that changes is the URL. Like Thumbs, page1, page2 etc.
